Charak Samhita
स्वरस्य दुर्बलीभावं हानिं च बलवर्णयोः। रोगवृद्धिमयुक्त्या च दृष्ट्वा मरणमादिशेत् ॥१२॥
॥ Poor prognosis with feeble voice॥ If a patient develops weakness of voice, diminution of strength and complexion, and aggravation of disease without an apparent cause then such patient will die soon.
